摘要：
A top emitting OLED includes two organic light-extraction layers on top of an at least partially transparent cathode. At least one of the light-extraction layers comprises an electron transport material and at least one of the light-extraction layers comprises a hole transport material. In some embodiments, the electron transport material is Alq3 and the hole transport material is a triaryl amine derivative.
